By Matt Rosenberg. A nations economy can be divided into various sectors to define the proportion of the population engaged in the activity sector. This categorization is seen as a continuum of distance from the natural environment.he packaging and processing of the raw material associated with this sector is also considered to be part of this sector. In developed and developing countries, a decreasing proportion of workers are involved in the primary sector.
RC SNUBBERS (SMPS) Snubbers are energy-absorbing circuits used to suppress the voltage spikes caused by the circuit's. inductance when a switch, electrical or mechanical, opens. The most common snubber circuit is a. capacitor and resistor connected in series across the switch (transistor).
In this circuit above the hot side of the line is switched and the load connected to the cold or ground side. The 39-ohm resistor and 0.01uF capacitor are for snubbing of the triac, and the 470 ohm resistor and 0.05 uF capacitor are for snubbing the coupler. These components may or may not be necessary depending upon the particular and load used.
